That’s the story of Slack, which began as a gaming venture named Glitch in 2013, only to pivot and skyrocket to fame as a go-to app for business collaboration. In just two years, it hit a milestone with over a million daily active users. By 2023, its worth had ballooned to a whopping US$26.5 billion, securing its spot as one of the tech world’s most rapidly growing Software as a Service (SaaS) companies. This journey isn’t just about luck; it’s a masterclass in growth hacking, the secret weapon businesses are using to stand out in today’s cutthroat market.
